PAPER CASE OR ENVELOPE.

To all whom it may concern:

Be it known that I, JOHN W. WiLooX, of the city of New York, and State of New York, have invented a new and useful Envelope for Filing and Preserving Documents and Papers, called the Excelsior Paper (Jase and Envelope; and I do hereby declare that the following is a full and exact description of the .same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The object of my invention is to construct a largeenvelope of stout heavy paper, to be used for filing or preserving papers and documcnts. To accomplish this object- I make an envelope in the manner illustrated in the ac coinpanying drawings. 7

Figure 1 represents the envelope open. Fig. 2 represents the envelope closed. Fig. 3 is a perspective view of one of the wooden end pieces A detached from the envelope.

A A are pieces of wood rounded at the ends and fastened to the ends of the envelope by nails or in any other manner which may be effectual. B is a metallic hook, held in its place by the eyelet O. D is an elastic loop, which passes through the eyelet E and is secured by the clasp F and closes the cnvelo e by being attached to the hook B.

My invention possesses the following advantages: The pieces of wood at the ends of the envelope increase its capacity, and by making them wider the capacity may be enlarged to any desired extent. They also prevent the ends and corners from being crushed and worn, and thus render the envelope durable. A convenient and secure fastening is also furnished by the elastic loop and metallic hook.

What I claim as new in my invention, and desire to secure by Letters Patent, is-

The pieces of Wood A A, fastened to the ends of the envelope, as and for the purpose shown and described.
